Angular Vs React: The Battle of JavaScript

What Should you build your front end in, Angular or React?


Angular is a comprehensive JavaScript framework with a google back end. It is a known framework across the community, and one widely used. It has everything needed to set up the client side and front end of a website. it provides a MVC (Model-View-Controller) patter that helps standardize the workflow of the application. Angular manipulates the DOM (Document Oriented Model) by extending the HTML with directives (newly created HTML constructs). It does this by offering two-way data binding. Any changes to the model are immediately reflected in the view and vice versa. This simplifies the application and reduces the amount of code needed to develop interactions and transitions.

Some the reasons that Angular has rose in popularity are: 1. Angular Directives, Dependency injection, Two way binding, solid tempting engine, on board form validation. Because of its popularity Angular has over 40,000 stars on its Github page and over 100,000 questions on StackOverflow, a leading question and answer forum.


React is a fast open sourced JavaScript library with a Facebook back end, and is considered the “new guy”.React caters to the view, and uses one way binding. The reason for its popularity is because it manipulates the DOM directly. It does this by having two copies of the DOM, the original version and an updated version that reflects the changed from the view. These two versions are run through a React function that figures out the difference between the two and what was actually changed. Because of this only the parts that are changing are affected by the changes in the view. This saves time and resources.

Beside speed there are few reasons people love React. 1. Server side rendering. React can be rendered on both the client and server side. This gives greater flexibility and gives the Virtual DOM breathing room. 2. JSX Files. This allows a single self contained component that tells exactly how it will render in the view. 3. React Native. This is a framework that enables you to build components for native UI widgets the same way you build them for HTML. React treats the view layer as a pure output of state, so switching its purpose from the web to mobile is easier.

Use React When

React shines best when you have a lot of dynamic content changing with the view. react is faster (maybe by about half a second) but speed is extremely important and the faster the better. also because it is a library you can use React as a view component of Angular or any other framework.

Use Angular When

Angular is best when development time is at a premium, and you need a full, comprehensive framework that will get you running quickly out of the box. Also if you want to create a single webpage Angular could be best. Another reason to use Angular is because React is not backward compatible with browsers older then IE8 and is young. Angular 2.0 has a huge performance boost, including support for server-side rendering and a similar approach to using one-way data binding to only manipulate the parts of the DOM that need to be changed.


Either way both are great ways to build a client side of an application. React is newer and faster, while Angular is older and because of that has a lot of resources online for help.
